How to choose a lithium battery

The portable lithium batteries circulating in the market are authentic imported batteries and domestically produced brand batteries. The non-authentic is the fake battery.

Original imported batteries are batteries that match the electrical appliances. The performance and compatibility of these batteries are certified, and they are also supported by the matching brand electrical appliances in terms of technology. Domestic batteries should be compatible with foreign brands of electrical appliances. Due to technological advances in domestic batteries, some international brands are gradually replacing the original brands with domestic lithium batteries, but they must use domestic well-known lithium battery brands.

The cost of the cottage battery is very low, and the inferior battery core is often used. After the battery is used for a period of time, the voltage drop is easy, the circuit is not protected, and it is easy to be damaged. The common electrolyte leakage and explosion in the news reports are caused by the cottage battery. .

In general, whether a lithium battery is authentic can be identified from the following aspects:

1. Is there a clear capacity? A battery without a clearly labeled capacity is likely to use a poor quality battery or a recycled battery. Many cheap batteries that are flooded in the market are made using recycled batteries. Although the price is cheap, the life is short and the quality is unstable. Inadvertent use may damage the mobile phone.

2. Is there a guarantee of standby time? Standby time is the continuous use time after the battery is loaded into the phone until the next charge. The batteries sold in the general market cannot guarantee the standby time for the customers. This is because the battery quality is unstable. Many inexpensive batteries use a battery with poor quality, so the standby time is short.

3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium battery is in danger of being deformed, leaking, or exploding. Under the vicious price-cutting competition, the companies are looking for a lower-cost protection circuit board, or simply omitting the device, making the market full of explosive lithium batteries. Consumers can't tell if they have a protective circuit board from the outside, so it's best to choose a reputable merchant to buy.

4. Attached with the product manual and the documents related to the sampling test of the battery by the technical quality supervision department.

5. When the battery is installed in the electrical appliance, feel comfortable and comfortable. The battery lock is partially and securely pressed.

6. The battery label is clear, there is a battery part number corresponding to the battery type, the corresponding position under the electrode is marked with "+", "-" mark.

7. Weigh the battery and see if the weight marked is the same as the actual weight. The weight should be within the error range.

8. Charging test. If the lithium battery does not charge for a long time and it gets hot, then the battery is probably defective.
